"Hi Guys
I have a F80 4 stroke Yamaha motor and it develops
a slight sqeak intermitently after about half an
hour to one our of use, it sounds like belt squeak
but i have placed a touch of lube on the belt while it is making the noise but have not been able to shut it up, i have also run the motor in a barrel but it seems i cant get it warm enough...
any ideas on what it could be"

"Could be the drive shaft bushing, drop lower unit and look up in there, maybe a dab of grease, maybe a new bushing. Good Luck!"
